- The changeless rule of network security
实现商用操作系统的安全加固 - Because that the process migration has almost been realized in the commercial operating systems , i . e . we can ’ t get the source code freely , the process migration won ’ t be used widely
由于进程迁移几乎都是在各商用操作系统中实现的,其源代码不公开,所以很难得到广泛使用。 - Oss is an adaptable layer to lower os . through the development based on lower os and the simple encapsulation of api interface , oss can shield the difference of the lower os api , provide the universal api to upper layer application and enhance the code portability
它主要是在底层商用操作系统的基础上通过二次开发，或简单的api接口封装，屏蔽掉底层各商用操作系统api之间的差异，为上层应用提供一组通用的api接口，增强了代码的可移植性。 - But there are several disadvantages about using linux in embedded application : linux can ’ t satisfy the real time application , there isn ’ t very mature integrate developing toolkit , it require advanced technique , and it isn ’ t more mature and steady than other commercial embedded os
但是在嵌入式应用中使用linux也有一些不足: linux系统不能充分满足实时性要求;没有十分成熟的集成开发工具;开发系统技术要求较高;没有商用操作系统成熟、稳定。 - The capsulation and extension of the functions form a virtual machine environment , programmes running on which appear to be the same as they do on a single pc , also , the difference between api interfaces in different commercial operating systems is masked , as well as meeting the transparence demands of operating system , and enhancing the transplantable ability of the applied programmes in the upper layer to a great extent
这些封装及功能扩展,构成了一个虚拟机环境,程序如同运行在pc机上一样。这就屏蔽了底层商用操作系统api之间的差异,就满足了rsp之上的应用层对操作系统透明性的需求,很大程度上增强了应用层(也称业务层)软件的可移植性。
